Averrhoa dolichocarpa is a wild starfruit from Papua and Averrhoa leucopetala is a wild starfruit from Gorontalo. Both starfruits have unique characters of the leaves, inflorescence, flowers, and fruits. The study was conducted from February 2012 to May 2012 by observing the wild starfruits collections of Bogor Botanical Garden. Innitiation of Averrhoa dolichocarpa inflorescence takes 8-14 days, the small bud growing in 11-15 days, after one day the large bud will open and the anthesis last after 3 days. The fruit will develop and mature after 40-45 days. The flower and fruit drop rate is quite high, mostly caused by strong wind. The chlorophyll content of the leaves are very dynamic and influence by the environment and the wide of the canopy. Whereas initiation of Averrhoa leucopetala inflorescence needs 30-34 days, the small bud growing in 12-15 days, the large flower bud will open after 1 day, anthesis last after 5 days, and the fruit development needs 40-42 days to mature. Anthesis of the flowers occurred at 4:00 to 6:00 a.m. The flower and fruit drop rate is also quite high. The chlorophyll content is more static and tends to increase when the fruit developed.

ASTUTI, I. P. & RUGAYAH. 2016. A new species of Murraya from Cyclops Mountain, Papua, Indonesia. Reinwardtia 15(2): 111 â114. â A living collection of Bogor Botanic Gardens, planted in plot XXIV.A.192-192a and originated from Kemiri Said Nature Reserve, Cyclops Mountain in Papua collected by Lugrayasa (LG 1352), is described and illustrated as a new species, namely Murraya cyclopensis Astuti & Rugayah. The species is closely related to Murraya paniculata (L.) Jack, in vegetative and flower structures, but differ in the presence of indumentum on twig, rachis and petiole, smaller size of flowers, red globose fruits, and orbicular seeds covered by densely short hairs and red aril.

Leaf anatomy of four species of Murraya (Rutaceae) have been examined. Murraya spp. leaf has dorsiventral type. Anticlinal epidermis cell wall present with straight-undulate and square-irregular shaped. Anomocytic stomata distribute only in the lower surface and simple trichome spread in both leaf surfaces except M. crenulata (Turz.) Oliv. which has trichome only in the lower surface. Mesophyll consist of 2 or more layers of palisade tissues in the leaf upper part and sponge below, but M. exotica L. has palisade tissue in both leaf side. Oil gland distribute in the mesophyll. Crystal present as prismatic (cuboid) and drusse type.

Pellacalyx is one of the genera in Rhizophoraceae, distributed from Myanmar, South China, Indonesia, Malaysia and the Philippines. In Indonesia, Pellacalyx can be found in the island of Sumatra, Kalimantan and Sulawesi. Eight species of Pellacalyx have been found Â in Indonesia, four of which them were from Kalimantan, i.e. P. axillaris, P. cristatus, P. lobbii and P. symphiodiscus. These four species generally grow in the primary and secondary forest, from lowland to an altitude of 1300 m above sea level. Information of Pellacalyx in Indonesia is still very limited , and rarely found in the wild. The last information of Pellacalyx found in West Sumatra was reported by an expedition team of the Center for Plant Conservation Bogor Botanical Garden in 2006. Â The Expert Team of the Khatulistiwa Expedition in Long Bagun, West Kutai, East Kalimantan on May 26âJune 2, 2012 found a species of Pellacalyx. Morphological characterization was then conducted based on the herbarium specimen for identification. The identification was carried out in Bogor Botanic Gardens, Center for Biological Research, Indonesian Institute of Sciences and The National Herbarium Leiden, Netherland. The results show that Pellacalyx specimen from Long Bagun is Pellacalyx symphiodiscus.Â

Rubiaceae is a cosmopolitan family of flowering plants distributed at almost all over the world. This family consists of 611 genera and 13,500 species. One of the 611 genera is Guettarda that has 50 to 160 species. Guettarda speciosa L. is one of species within Guettarda which is distributed from East Africa to the Pacific Islands including Indonesia. The objective of this study, therefore, was to determine the species’ distribution in Indonesia and its potential use. The data was collected from herbarium specimens deposited in Herbarium Bogoriense, field collection data from exploration by Center for Plant Conservation, Indonesian Institute of Sciences, and NKRI Expedition in West Papua. Based on the collected data, an analysis was conducted to create distribution map of the species. Information related to the potential use of this species in Indonesia showed thatit iscommonly used as ornamental plant, although Rumphius reported that in Ambon the wood or bark of this species was usually boiled together with root ofArtocarpus as a traditional medicine for diarrhea.

HOYA DECIPULAE (APOCYNACEAE, ASCLEPIADOIDEAE), A NEW SPECIES FROM SUMATRA Rahayu, Sri; Astuti, Inggit Puji

RAHAYU, S. & ASTUTI, I. P. 2018. Hoya decipulae (Apocynaceae, Asclepiadoideae), a new species from Sumatra, Indonesia. Reinwardtia 18(1): 61‒67. ‒‒ The new Hoya species from Sumatra, Hoya decipulae S.Rahayu & Astuti is here described and illustrated. It is an epiphytic shrub, thin-leaved with white flowers, similar to those of H. papaschonii Rodda, but differs in corolla and corona form. Its corolla has a unique characteristic of forming a “cage” before fully opening, as a result of the attachment of the five corolla tips which are free at the centre. The corona does not have interstaminal lobes as in Hoya papaschonii. Its corona resembles that of H. multiflora Blume and H. irisae Ferreras, Kloppenburg & Tandang from the centre to the tip but differs at the base.
